Length modifiers can be:
- Byte-length modifiers —
where the value of the modifier determines the number of bytes of
storage allocated to a constant.
- Bit-length modifiers —
where the value of the modifier determines the number of bits of storage
allocated to a constant.
When no length is specified, for character and graphic constants
(C and G), hexadecimal constants (X), binary constants (B), and decimal
constants (P and Z), the whole constant is assembled into its implicit
length.
